Recently Sujan Patel from Single Grain came with an excellent post regarding the recent changes in SEO & things every SEO Professionalsneed to know there are big changes came in algorithm of major search engines  that really changed the way of thinking. The first one Sujan covered in “Google Panda 3.7″. Lets see what he mentioned in his blog for Single Grain –

On June 8th, 2012, Google rolled out a minor refresh of the Panda algorithm called Panda 3.7, which the search giant claimed noticeably affected only 1% of all search queries.

Because this update was labeled a “refresh,” no changes were made to the algorithms or to the weighting of the specific ranking factors accounted for by these equations.  Instead, Google simply reapplied the existing Panda algorithm to its search indices, resulting in changes to the organization of the SERPs only because the number and quality of sites indexed by Google has changed since the last refresh.

Another move of rewarding quality sites launched this year. Now you must have to come with useful and informative contents with great quality for getting top position of search engine result pages.

After two weeks , Google launched its second update labeled Panda 3.8. However, lets take a look what it means –

Just two short weeks after the Google 3.7 refresh, Google rolled out another Panda data refresh – this one labeled as “Panda 3.8” – on June 25th, 2012.  Again, the impact of this update was relatively small, with Google estimating that around 1% of search queries were affected.

As both Panda updates 3.7 and 3.8 were launched without significant changes being made to their underlying algorithms, we aren’t recommending any changes to the established SEO best practices we’ve discussed thoroughly on this blog before.

This is again a tweaking on 3.7 that actually  affected 1% searches and there were no significant changes in SEO best practices were suggested by the experts.
